Frequently Asked Questions
What is ROI?
ROI (Return on Investment) is a percentage measuring the profitability of an investment relative to its cost. ROI = (Net Profit / Cost of Investment) x 100%.
What is annualized ROI?
Annualized ROI converts any period's return into an equivalent annual rate, allowing fair comparison between investments held for different lengths of time.
What is a good ROI?
A good ROI varies by context. The S&P 500 historically returns about 10% annually. Any ROI above the risk-free rate (treasury bonds) can be considered acceptable.
What information do I need to input into an ROI calculator?
The core inputs for an ROI calculator are your initial "investment amount" and the "return amount" or "final value." The investment amount includes all costs associated with the venture. The return amount is the total revenue or profit generated. Some calculators might also ask for the investment duration to compute annualized ROI, providing a comprehensive view of your investment's financial performance.
How can an ROI calculator help me compare different investment opportunities?
An ROI calculator is invaluable for comparing multiple investment options by providing standardized metrics. You can quickly input varying investment costs and potential returns to see respective ROI percentages, annualized ROI, and net profit figures side-by-side. This allows for an objective assessment, helping you identify which opportunity offers the most favorable financial outcome relative to its cost and duration, leading to more informed decision-making.
